GAS REMOVING MACHINE May 23, 1933.

d July 5, 1928 Patented May 23, 1933 UNITED STATES LOUIS KESSLER, OF CHICAGO, ILLINOIS PORTABLE AIR DELIVERING ANnGAs REMovINe MACHINE Application filed July 5, 1928, Serial No. 290,451.

In making excavations in cities and elsewhere, sew-er gases and other noxious gases and fumes are frequently encountered and these should be removed and supplanted by 5 fresh air to insure the safety of the workmen.

The object of the present invention is to produce a simple and novel machine adapted, if desired, simultaneously to withdraw gases or fumes from a considerable number of distributed points.

In carrying out my invention I mount a motor driven blower on a small truck, providing the inlet of the blower with a detachable manifold to which any desired number of suction conduits may be attached; Gases or fumes may be collected by means of these conduits at selected points. Or, if it be desired to force fresh air into a cavity, the manifold may be removed and aconduit be attached to the discharge side of the blower to carry fresh air to the desired location.

Therefore, viewed in one of its aspects, the present invention may be said to have for its object to produce a simple and novel portable machine by means of which gases may be drawn from a given point, or, on the other hand, fresh air be effectively de livered at that point.

The various features of novelty whereby my invention is characterized will hereinafter he pointed out with particularity in the claims; but, for a full understanding of my invention and of its objects and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawing which is a perspective view of the machine arranged in accordance with my invention.

Referring to the drawing, 1 represents a flat truck body mounted on suitable wheels of which two, 2 and 3, are shown; a suitable handle 4 being provided for moving the truck around.

On one end of the truck is mounted a motor driven blower unit 5. Current is supplied to the motor through a cable 6 interrupted by a suitable switch 7. When not in use, the cable may be wound on a suitable reel 8 mounted on the truck.

The inlet for the blower is a large nipple 9. Detachably connected to the nipple is. a long manifold' lO. The connection between thenipple and the manifold may conven- Iently be in the form of a pipe coupling 11 about midway between the ends of the manifold. In the arrangementshown, the parts are so proportioned that the manifold is simply turned bodily so as to be screwed on and off in the manner of a nut. Where the manifold is long,-the truck body may-have a' window 12' cut through the same to provide clearance for the rotating manifold wien the latter is turned 'to screwit on 'or o I The manifold is provided with any desired number of inlets in the form of short pipe sections 13. These inlets may be closed by means of caps 14. Interchangeable with i the caps are suction conduits of which one is shown at'1 5. Each'suction conduit is preferably provided with a perforated head 16 at its inlet end.

As many conduits are connected to the manifold as there are 'points from which gases or fumes are to be withdrawn, the other inlets in'the manifold being closed by means of the caps, The suction conduits are made flexible so that the inlet ends may be moved about over comparatively wide areas withput changing the position of the machine itsel In the event that fresh air is to be forced into a cavity of any kind, the manifold is detached so as'to permit air to be drawn freely into the inlet side of the blower. A suitable conduit, not shown, but which may be in the form of a hose, is connected to the discharge side of the blower. The discharge outlet from the blower is therefore made through a tubular member 16 having thereon 9o lugs 17 or other suitable means for quickly detaching a hose thereto.

It will therefore be seen that I have produced a simple and novel machine that may be transported to the point of use and moved about with little effort, and which will permit fumes or gases to be collected simultaneously from numerous distributed points; and by means of which, if desired, fresh air may be carried to and delivered at any desired point Without interference from the means employed to collect gases or fumes.

WVhile I have illustrated and described with particularity only a single preferred form of my invention, I do not desire to be limited to the exact structural details thus illustrated and described; but intend to cover all forms and arrangements which come Within the definitions of my invention constituting the appended claims.

I claim 1. A machine of the character described comprising a small truck, a motor driven blower mounted on the truck, a reel on the truck adjacent to the blower, a cable for supplying actuating current to the blower adapted to be wound on the reel when not in use, said blower having an inlet in the form of a large nipple, a manifold extending transversely across the top of the truck in the plane of the nipple, a pipe coupling connecting said nipple to the manifold midway between the ends of the latter, said manifold having numerous inlets distributed throughout the length thereof, closures for said inlets, and suction conduits interchangeable with said closures.

2. A machine of the character described comprising a small truck, a motor driven blower mounted on one end of the truck, said blower having an inlet in the form of a large nipple, a manifold extending transversely across the top of the other end of the truck in the plane of the nipple, a pipe coupling connecting said nipple to the manifold midway between the ends of the latter, said manifold having numerous inlets distributed throughoutthe length thereof, closures for said inlets, and suction conduits interchangeable with said closures.

In testimony whereof, I sign this specification.
